Title: Optical recording medium
Inventor: OOSATO YOUICHI
IPC: G11B7/24
Filed: 1983-03-22
Abstract: PURPOSE:To ensure the optical recording with high density and large capacity by producing a recording layer where the recording sensitivity is varied along the radius direction, and making approximately pit form equal at both the most inner and the most outer circumference parts of a disk. CONSTITUTION:A recording layer 30 contains a glass substrate 31, an intermediate layer 32, a photosensitive layer 33 whose optical characteristics or form is varied with heat to sense the heat and absorb the light, and a reflection preventing layer 34 which functions to increase the light abosrbing effect of the layer 33. Either one of layers is selected with exclusion of the substrate 31, and the film thickness of this selected layer is consecutively changed along the radius direction of a recording medium. For instance, the film thickness of the layer 33 is increased at its most outer circumference part. Thus it is possible to change the sensitivity of the layer 30 along its radius direction. Therefore an approximately equal pit form is obtained at both the most inner and most outer circumference parts of a disk. This ensures the recording with high density and large capacity.

Abstract: PURPOSE:To eliminate the necessity to which the control unit of an address for referring to a dither table correspondingly to the requested number of gradations to be added in the case of executing dither modulation. CONSTITUTION:When it is desired to selectively use the dither table of 3X3 and the dither table of 4X4, a storage space 100 of 12X12 is prepared as a storage space.

Filed: 1988-03-01
Abstract: PURPOSE:To make it possible to grow an InP layer on an InGaAs layer by a method wherein a melt on an InP substrate subsequent to an epitaxial growth is removed. CONSTITUTION:A wiper 11 for wiping off a melt on a semiconductor substrate material interlocking melt reservoirs 3 is provided. First, a grown melt 9 is once removed up completely by the wiper 11 after the growth of an InGaAs layer 200 and in that state, the temperature of an InGaAsP antimeltback layer 300 is dropped up to 630 deg.C or below. As the solubility of the InP melt becomes very small at a temperature of 630 deg.C or below, the melt is not melted back even though being brought into contact with the layer 200 and an InP layer 400 is epitaxially grown. Thereby, the growth of the InP layer on the InGaAs layer and the like can be grown without making the melt back and furthermore, a quench melt at the time of the end of growth becomes unnecessary.

Abstract: PURPOSE:To eliminate an interruption of the address transfer by controlling the first-in/first-out of a real address memory for each page which is converted from a logical address after detecting the arrival at the page limit. CONSTITUTION:If a channel designating signal 6 designates an address memory 10 which fetches a real address 12 converted from a logical address for each page, a corresponding address register 11 becomes enable via a decoder 4. Then a transfer address 7 given from the register 11 is updated by a replacement mode indicating circuit 5, an address replacement circuit 2, etc. every time the address 7 from the register 11 is delivered. Then the address of the page belonging to the address 12 supplied to the memory 10 is transferred. While a page boundary detecting circuit 3 shared by each channel detects the page limit for the transfer address. Based on this detection signal, the first-in/first-out of the memory 10 is controlled via an address transfer control circuit 1. Thus no interruption occurs to the address transfer, and no request is needed for a high- speed conversion of address.
